    摘要: Yeast promoters of glycolytic enzymes are modified by isolating a fragment encompassing the RNA polymerase binding site and joining to the 5' end of this fragment a DNA sequence providing for enhanced inducible or constitutive transcription of a structural gene. Constructs are prepared for efficient expression of foreign genes in yeast.Yeast strains 2150-2-3 (pC1/1GAPSOD) and AB110 (pC1/1GAPATi9), producing human .alpha..sub.1 -antitrypsin and superoxide dismutase, were desposited at the A.T.C.C. on May 9, 1984 and given Accession Nos. 20708 and 20709, respectively; and 2150-2-3 (GAP5), 2150-2-3 (Pyk5) and 2150-2-3 (PHO5GAP1), expressing Hepatitis B surface antigen, were deposited at the A.T.C.C. on May 9, 1984 and given Accession Nos. 20705, 20706 and 20707, respectively.

    摘要: Methods and compositions are provided for efficient expression of genes in unicellular microoorganisms, particularly yeast. The systems involve an expression system employing transcriptional initiation regions from glycolytic enzymes, particularly a chimeric expression system, having a first region providing for regulatable or constitutive expression, a second region providing for transcriptional initiation, where regions one and two are not found joined together in functional relationship in nature, and optionally a sequence providing for a secretory leader and processing signal, where the expression cassette will be joined to a gene which may be homologous or heterologous to the host. The expression cassette can be used on an extrachromosomal element or integrated into the host genome, whereby continuous expression can be achieved or inducible expression is obtained, by virtue of the presence or absence of an inducer. Constructions may be provided, where structural genes may be introduced in reading frame with the cassette to provide for expression of the natural peptide, a fused peptide, or a peptide precursor.The S. cerevisiae strain AB110 (pAB24/P. vivax 1-5 was deposited at the A.T.C.C. on May 9, 1986, and given Accession No. 20797.

    摘要: Proteinaceous composition are provided which inhibit naturally occurring serine proteases. Particularly, an amino acid sequence analogous to human .alpha..sub.1 -antitrypsin is modified at the active site while maintaining protease inhibition. The methionine at the active site is substituted with an oxidatively stable amino acid, while other amino acids may also be changed, added or deleted, particularly at the termini.The yeast strains AB103.1 (pCl/PH05ATi(Val) and AB110 (pCl/1GAPATi(Val) were deposited at the A.T.C.C. on June 18, 1984 and given Accession Nos. 20711 and 20712, respectively.
